IIRC you can read them pretty easily as the kMDItemFinderComment metadata attribute. Setting them is harder.
The comments are stored in two places, AIUI --- an extended file attribute (com.apple.metadata:kMDItemFinderComment xattr) and in the .DS_Store file (maybe only on older OS revisions) --- neither of which seem like things other apps should mess with directly. I think the most-nearly-supported way to do this is still to send an aevt to the Finder (set the <comt> property of the file to the text you want).
Some example code here, though be aware it was mostly written in the 10.4 timeframe: https://github.com/omnigroup/OmniGroup/blob/master/Frameworks/OmniAppKit/OpenStepExtensions.subproj/NSFileManager-OAExtensions.m
Technote 2045 seems to have vanished softly and silently away from the web, but it's still available in Xcode's embedded document viewer.
